Takara's AMWDW- Personal Judgment in the Fandom

That was supposed to be a bit of a JOKE. He is listening to what I'm saying, I just wanted to throw in the Eye Contact part, because it's something I struggle with from time to time. 

If you're wondering what it is we're talking about however, it's a situation that might be a little too controversial and personal to use in an actual AMWDW, which is a thought that I'm still pondering, but it is something I wouldn't mind given closure off of. 

After seeing all sorts of different stories on the news, that seem to be controversial, and growing up in a family that raised me to be cautious of these sorts of situations (I want to thank them for that), I've come to have a sort of a fear of strangers. DON'T GET ME WRONG, I don't have anything against anyone in the fandom; for what it's worth, I believe a lot of people in the fandom have some good aspects and bad ones, and the good aspects can outweigh the bad aspects now and then. But whenever I receive something like a DA Note, an email, or even a comment on YouTube, I feel my breath get heavy and mind race, wondering who it's from. 
Sometimes I have moments where I wonder whether or not I'm trusting enough of others in the fandom, or that I'm placing judgment onto others without even knowing who/how they are, but when I talk to somebody else about it in real life, they commend me for knowing what to do in these situations; that I understand that these things can and will happen, and that I'm protecting myself in turn. I don't necessarily believe it 100%, but a small part of me is proud that I'm willing to keep myself safe. 

So I have to ask. How much trust can one put into other people they meet in a fandom, and how much judgment can we even out in a situation?
